nse-js
nse-js is a Node.js library for fetching data from the National Stock Exchange (NSE) of India. It provides various methods to retrieve market data, circulars, option chains, corporate actions, and more.
[!IMPORTANT] This module is not yet ready for production use as it's not tested on production environment.
Installation
npm install nse-js
API limits
All requests through NSE are rate limited or throttled to 3 requests per second. This allows making large number of requests without overloading the server or getting blocked.
- If downloading a large number of reports from NSE, please do so after-market hours (Preferably late evening).
- Add an extra 0.5 - 1 sec sleep between requests. The extra run time likely wont make a difference to your script.
- Save the file and reuse them instead of re-downloading.
Usage
